Total Property Tax: Joining Federal CGT, Land Tax and Stamp Duty

How the new federal property tax rules, land tax and stamp duty stack together — and what to check on any potential purchase this week before you sign.

Key Takeaway

New federal property tax rules interact with state land tax and stamp duty by increasing long‑term capital gains tax and restricting negative gearing, while states still control upfront duty and annual land tax. This means investors must now treat stamp duty as a 7–10 year break‑even drag in many markets and budget for higher after‑tax CGT at sale. The actionable step is to model entry, holding and exit taxes together before buying or restructuring a property.

How the new federal property tax rules, land tax and stamp duty stack together — and what to check on any potential purchase this week before you sign.

The new federal property rules mainly change capital gains tax (CGT) and negative gearing, while states still control stamp duty and land tax. Together they decide your real, after‑tax return. To act this week, treat them as one stack: duty when you buy, land tax while you hold, federal tax when you sell.

Diagram of stamp duty, land tax and CGT stacking on an Australian property. Think of stamp duty, land tax and CGT as stacked taxes on the same property over time.

1. The three big property taxes, in plain English

Think of the system as three layers on the same property:

Stamp duty (state) – once‑off tax when you buy, based on price and buyer type.
Land tax (state) – annual tax on unimproved land value above each state’s threshold.
CGT and income tax (federal) – tax on rent each year and capital gain when you sell.

From 1 July 2027, most individuals lose the 50% CGT discount and move to CPI indexation plus a 30% minimum tax on real gains (see /insights/updated-cgt-rules-geared-property-investors-2027-playbook). At the same time, negative gearing on many established properties bought after 12 May 2026 is effectively removed for wage earners.

Quick example: one unit, all taxes

Buy $800,000 established unit in NSW in 2027, 80% LVR.
Stamp duty: roughly $32k–$35k upfront (varies with rules and concessions).
Land tax: say $3k/year once over threshold.
Federal tax: rent taxed annually; on a $300k real gain, at least $90k CGT under 30% minimum.

Individually, each looks manageable. Stacked, they materially change your required growth and holding period.

2. How the new federal rules change state‑level maths

The federal changes don’t alter state tax law, but they change how hard stamp duty and land tax bite. ### a) Stamp duty now needs a longer holding period Stamp duty and transaction costs already mean many buyers need 7–10 years to break even in high‑price markets (see /insights/renting-nearby-vs-buying-bronte-2026-numbers). With: * less or no negative gearing benefit on new established investments; and * higher CGT at sale, shorter holds look even worse. Flipping an investment after 3–5 years will often mean: * limited real growth after inflation; * full land…

Frequently asked questions

They don’t change your actual land tax assessment, which is set by each state based on land value and thresholds. However, with negative gearing restricted for many new established investments, you may no longer get a tax refund that effectively softens the impact. That means land tax should now be treated as a full cash cost in your annual budget, not something the ATO partly hands back.

You don’t have to delay, but you do need to run the numbers under the new regime, particularly if you’re buying an established dwelling. Model cashflow assuming no tax benefit from early rental losses and a 30% tax on real capital gains at sale. If the investment still looks solid on those assumptions, waiting solely for rule clarity may cost you time in the market.

Owner-occupiers are affected indirectly rather than directly. Your main residence is usually exempt from CGT, and you don’t pay land tax on your home in most states. However, the new rules can influence investor demand, rents and long-term market dynamics in your area, which may affect your upgrade, downsizing or rentvesting plans over the next decade.
